The earth-skimming tau neutrino detection technique

This detection technique has been proposed originally by Dr. Fargion and others,
(Astrophysical Journal, 570 (2002) pp.909-925, based on their researches in 1997).


Figure 5: Schematic view of the earth-skimming neutrino detection technique.
The right mountain is Mauna Kea, and the left is Mauna Loa.
Incident tau neutrino converts to a tau lapton via charged current interaction with the rock,
to exit to the atmosphere and generate a detectable air-shower.

Energy of incident neutrinos is fixed to 10^17 eV. Grids show our trigger pixelization.
